Hitachi GST announced Wednesday the launch of their new Ultrastar SSD400S.B enterprise-class line of SSDs. Using a Serial Attached SCSI (SAS) 6Gb/s interface, the drive packs a wallop. It can handle up to 536/502 MB/s sequential read/write, respectively, with 57,500/25,500 read/write IOPS. They come in 100GB, 200GB, and 400GB sizes. And since they're enterprise drives, they're also built to be reliable. In the lifetime of the drive, they withstand up to 35 petabytes of random writes. According to the press release, this is equivalent to writing 19.2TB per day for five years. Ultrastar SSDs are also the first to use 25nm SLC technology, which is probably another reason why the performance is so amazing. Internally, the NAND flash memory is from Intel, but it didn't say what controller it uses. Something that is puzzling to me is that Hitachi GST is releasing the drive instead of Western Digital. Almost a year ago Western Digital announced that they were going to buy the company, and the deal was expected to go be done by the third quarter of last year. The drives are available now, and the company is working with OEMs to get them out on the market.
